Abstract

The effect of the atmospheric pressure plasma(APP) treatments is experimentally investigated to ascertain the optimum condition to yield the best adhesive properties between a polyamide woven fabric and acrylonitrile butadiene rubber(NBR). For the atmospheric pressure flame plasma(APFP) treatment, the optimum number of treatment at given conditions is 2 times. The thermal deformation of the fabric is more serious with increasing the number of APFP treatment. The adhesive strength of the case with APFP treated fabric is increased about 35% when compare to the case with non-APFP treated one for the interface(bonding agent one or two coatings). When the surface is coated twice with the bonding agent, the adhesive energy with APFP treated fabric is increased about 4 times. It was found that the surface modification of polyamide woven fabric by APFP treatment is a fast, economic and applicable method to improve the adhesive properties between woven fabric and rubber when compared to other APP treatments.

폴리아미드 직물과 NBR의 최적 접착특성을 나타낼 수 있는 조건을 검토하기 위해 대기압 플라즈마(APP) 처리 효과에 대한 실험적 연구를 하였다. 대기압 화염 플라즈마(APFP) 처리의 경우 주어진 계면조건에서 최적의 처리횟수는 2회였다. APFP 처리 횟수가 증가함에 따라 직물의 열변형은 더욱 심하였다. APFP 처리 직물을 강화한 복합재료의 접착강도는 접착제를 한번 혹은 두번 도포한 계면에 대해 플라즈마를 처리하지 않은 경우에 비해 약 35% 증가하였다. 접착제를 중복 도포하였을 때, APFP 처리 직물 강화한 복합재료의 접착에너지는 약 4배 증가하였다. APFP 처리에 의한 폴리아미드 직물의 표면 개질이 다른 형태의 APP 처리방식과 비교했을 때, 경제적이고 빠르며 고무와의 접착강도를 개선시킬 수 있는 방법이라고 판단된다.
